JP4555597B2 - Hydrogen pump for microtus - Google Patents

Description

The present invention relates to a micro-total system (micro-total analysis system).
It is related with the hydrogen pump used for stem).

Recently, there is a great need for technology to diagnose and analyze at low cost in the field, such as bedside diagnosis in the vicinity of patients, monitoring of environmental pollutants in the air, water and soil, and food safety inspection. It is getting higher.

For example, if an analysis that previously required an expensive and large device could be replaced by a small portable analyzer, a practitioner could install and use an analyzer that could only be installed in a large hospital. Thus, the diagnosis result can be easily and quickly fed back to the patient.

In addition, the elderly's health index is measured by the elderly's family and the health index value is managed at home.
The home medical environment becomes more excellent by regularly sending to the hospital and managing it at the hospital.

If environmental pollutants such as environmental hormones and dioxins can be easily measured without using an expensive and large apparatus, environmental diagnosis can be performed easily and inexpensively. Furthermore, if environmental pollutants can be analyzed on site using a small portable analyzer, a more detailed safe environment can be provided.

In order to perform such measurement easily, a fine flow path, an infusion device,
Reaction tank, electrophoresis column, membrane separation mechanism, liquid chromatograph column, capillary gas chromatography (CGC), capillary chromatography (ILC), induction plasma (I
CP), mass spectrometers (MS), electrochemical measuring devices and the like have been actively studied on microtus systems.

In the microtus system, a micropump is generally used as an infusion device for transporting a liquid such as a sample or an eluent.

Examples of the micropump include a diaphragm, a driving unit that reciprocates the diaphragm, a pressure chamber partially defined by the diaphragm, a displacement measuring unit of the diaphragm, and a value detected by the displacement measuring unit. The diaphragm pump (for example, refer patent document 1) provided with the control means which controls the displacement of the said diaphragm based on this.

Further, as a different micropump, the first moving the piston and the housing relative to each other is possible.
Actuator, a cylinder having at least a part of the piston and having a space penetrating in the axial direction, a second actuator for relatively moving the cylinder and the housing, and the piston, the cylinder, and the housing Fluid supply device (for example, refer to Patent Document 2) composed of a pump chamber that is connected to the pump chamber and the outside, and a method for generating an electroosmotic flow on a fine channel (For example, refer patent document 3) etc. which perform liquid feeding of the liquid feeding medium by (1).
JP 2001-132646 A JP 2002-021715 A Japanese Patent Laid-Open No. 10-10088

However, the structure of the micro pump is complicated, and the creation effort of the pump is very large compared to the effort of creating the concentration part and the detection part.Pumps with a diaphragm structure or a piston structure cause pulsation in the liquid feeding medium. The pump using the electroosmotic flow has a drawback that a high voltage needs to be applied.

Furthermore, it is possible to form all materials other than the electrode and the wiring with a polymer resin having good processability without the above-mentioned drawbacks, and a hydrogen pump (for example, a micropump that can be easily made extremely small) However, it is difficult to manufacture a hydrogen pump that can be built in a microtus system. In particular, it is extremely difficult to incorporate a plurality of hydrogen pumps in one microtus system.

Reference numeral 9 denotes an insulating film such as a polyimide film, which is interposed between the conductor lead 4 and the solid electrolyte membrane 1 so that the conductor lead 4 does not contact the solid electrolyte membrane 1.

As the flame retardant hydrogen permeable base material 2 ′, any base material that is flame retardant and has hydrogen permeability can be used. However, since a high temperature may be applied when forming the carbon layer, glass fiber is used. The woven or non-woven fabric is preferred.

As a method for forming the hydrogen permeable electrode 3 ′ made of the carbon layer, any conventionally known method may be employed. For example, a method of applying and drying a conductive paint containing carbon black may be used.

However, since the carbon layer needs to be hydrogen permeable and preferably has excellent electrical conductivity, after the polymer resin composition is applied to the flame retardant hydrogen permeable substrate 2 ′, non-oxygen It is preferably formed by firing in an atmosphere.

The polymer resin composition may be a composition containing a polymer resin that can be carbonized by firing in a non-oxygen atmosphere. Examples of the polymer resin include polyolefin resins, polystyrene resins, and polyresins. Examples thereof include thermoplastic resins such as lactic acid resins, polyacrylic resins, polycarbonate resins, and polyester resins; and thermosetting resins such as epoxy resins, phenol resins, unsaturated polyester resins, and polyimide resins.

The polymer resin composition is made of a polymer resin such as alcohol, acetone, ethyl acetate, toluene, methyl ethyl ketone, tetrahydrofuran, or dimethylformamide so that the resin composition can be easily applied to the flame retardant hydrogen permeable substrate 2 ′. An organic solvent that can be dissolved or dispersed may be added.

In order to impart conductivity, carbon black particles, graphite, carbon fibers, metal particles and the like may be added.

Firing in the above non-oxygen atmosphere means heat treatment without burning the polymer resin under vacuum or an inert gas atmosphere such as nitrogen, argon, neon, etc., and elements other than carbon of the polymer resin To form a carbon layer.

When the hydrogen permeable electrode 3 ′ is formed by baking the polymer resin composition in a non-oxygen atmosphere, the polymer resin composition is applied to the flame retardant hydrogen permeable substrate 2 ′. Alternatively, it is preferable that after the application, a conductive paint containing highly conductive metal particles and the above polymer resin is applied and fired in a non-oxygen atmosphere to form the hydrogen permeable electrode 3 ′ and the conductor lead 4 simultaneously.

Since the flame retardant hydrogen permeable base material 2 ′ is hydrogen permeable, the generated hydrogen may leak to the adjacent hydrogen permeable electrode, so that the generated hydrogen does not leak to the adjacent hydrogen permeable electrode. As described above, a portion other than the hydrogen permeable electrode of the flame retardant hydrogen permeable substrate 2 ′ is subjected to a known treatment such as impregnation with a resin that is non-permeable to gas, and thus flame retardant hydrogen permeability is achieved. It is preferable that the hydrogen permeable electrodes of the base material 2 ′ are insulated.

Further, that the gas is non-permeable means that the gas is substantially non-permeable.

As a method of impregnating the above-mentioned insulating resin into the flame-retardant hydrogen-permeable base material 2 ′, any conventionally known method may be employed. For example, a method in which the resin is heated and melted and pressed, an insulating resin solution is difficult to be used. Examples include a method of impregnating a flammable hydrogen-permeable base material and then drying by heating or curing.
